MINOR: ssl: load the sctl in/from the ckch

Don't try to load the file containing the sctl each time we generate a
SSL_CTX.

The .sctl is now loaded in the struct cert_key_and_chain only once and
then loaded from this structure when creating a SSL_CTX.

Note that this now make possible the use of sctl with multi-cert
bundles.
